Oil, like salt, wheat, and those too-sweet rainbow popsicles in your freezer, is one of those items we don’t think has an expiration date, but it won’t last forever like anything fresh. Always check for rancidity in your oil before using it. It is not suggested to consume rancid oil because it might be harmful to your health in the long run. Rancid oil can cause intestinal discomfort and give your food a bad taste in a short period.
The oil that hasn’t been opened and kept in a dry, relaxed environment can survive up to two years.
